Well Ebert will be giving this a thumbs down, with his line of reasoning being "why did the director who made a movie about a nice robot boy make a movie about robot wars," which is what happened when Ebert tried to compare War of the Worlds to E.T.
Hardly. He did a great deal better than that.
He did, however, reference a great deal of Spielberg's previous work in eviscerating the thing on the basis of story logic and plot.
Ebert's one of a dying breed - American movie reviewers who know something about film and the history of film, have lived lives and don't think bloviating into a webcam for posting to YouTube constitutes a body of work.
